Abstract: A display device includes a backlight, a pixel controlling unit, a power driving unit, a source driving unit which transmits, to the pixel controlling unit, intensities of the LEDs connected to the pixel controlling unit, and a timing controlling unit. The pixel controlling unit adjusts, in a first time section, an intensity of a first LED based on a first intensity received from the source driving unit, wherein the first LED is connected to a first line which is activated by the power driving. The pixel controlling unit adjusts, in a second time section different from the first time section, an intensity of a second LED based on a second intensity received from the source driving unit, wherein the second LED is connected to a second line which is activated by the power driving unit.
